Muscle nerve injury symptoms?

summary

Recently, a colleague had some abnormal physical conditions, mainly muscle atrophy and hardening. Later, he went to the hospital for examination and got the disease of muscle and nerve injury. Let's introduce the symptoms of muscle and nerve injury.

Muscle nerve injury symptoms?

First, muscle neurogenic damage is commonly seen in amyotrophic lateral sclerosis, with an incidence rate of 1/10 million, and some areas as high as 40/10 million. Amyotrophic lateral sclerosis (ALS) is an upper and lower motor palsy caused by anterior horn cell lesion, progressive damage of medullary motor nucleus and pyramidal tract（ Electromyography showed neurogenic lesion and anterior horn cell lesion. The increase of creatine kinase in some patients indicates that muscle damage is also caused by family factors, viral infection, immune deficiency, metal poisoning, deficiency of some elements (deficiency of thiohydrogen sh function of intracellular enzyme system), trauma and alcoholism, which damages brain stem, spinal cord nerve and spinal gray matter. The results of electron microscope showed that there were virus like particles in the dead patients. Most of the familial patients had autosomal dominant inheritance.

Second, typical pathological changes are degeneration of lower motor neurons in spinal cord and medulla oblongata, involvement of pyramidal cells in cerebral cortex, degeneration of corticospinal tract and cortical medulla oblongata, involvement of pyramidal cells in cerebral cortex, degeneration of corticospinal tract and cortical medulla oblongata, demyelination and invasion of other parts of central nervous system There were inclusion bodies in the cytoplasm of anterior horn cells and cranial motor nucleus, degeneration of neurons in spinocerebellar tract and retractable column, involvement of posterior funiculus substantia nigra globus pallidus and locus coeruleus cranial nucleus. After getting sick, the symptoms of different patients will be different due to their different conditions. We should pay attention to the abnormal phenomenon of muscles psychologically.

Third, the syndrome can be divided into sporadic type, guateman type and family genetic type. Most patients had myofibrillar tremor of the distal upper limb in the early stage, followed by muscle atrophy and muscle weakness. A few patients had muscle atrophy and lower limb weakness first. In some cases, the muscles of the hand (Hegu acupoint) begin to atrophy, and the muscle bundles tremble. Due to the atrophy of the tongue muscle, the tongue is inflexible in the mouth when speaking, and the words are not clear. When drinking water, the epiglottic cartilage does not cover the trachea tightly, and the water drops are easy to enter the trachea, resulting in choking, dysphagia, signs of pyramidal tract of limbs or lower limbs, hyperactivity, late paralysis, bulbar paralysis, respiratory crisis, and termination of life.

matters needing attention

The disease of muscle and nerve injury should be found, checked and treated early, especially in the treatment, the daily diet is also particularly important, and some food therapy methods play an important role in the treatment of the disease.
